not needed:
* devm_input_allocate_device - allocate managed input device
* @dev: device owning the input device being created
*
* Returns prepared struct input_dev or %NULL.
*
* Managed input devices do not need to be explicitly unregistered or
* freed as it will be done automatically when owner device unbinds from
* its driver (or binding fails). [...]
